Universal 3D File
An open standard for 3D data exchange, originally developed by the 3D Industry Forum to enable universal 3D visualization across platforms. As a compressed, binary file format, U3D efficiently stores three-dimensional triangular meshes along with additional properties such as color, transparency, or texture coordinates.
Key Features of U3D
- Open Standard: Royalty-free format maintained by ECMA International (Standard ECMA-363).
- PDF Integration: U3D enables the generation of PDF documents that contain interactive 3D data (ISO 32000). This means that you can view, rotate, zoom, and manipulate 3D models within a PDF document.
- Compact Size: Optimized compression for web and document embedding.
- Cross-Platform: Viewable across major operating systems without proprietary software.
U3D File Conversion
Our Autoconverter and Automesher Application utilize Intel's powerful open-source IFX conversion library to deliver robust U3D file conversion capabilities. This technology enables seamless two-way conversion between the U3D format and various industry-standard 3D formats including STL, OBJ, SKP, DAE, STEP, IGES, DWG, 3DS, FBX and X3D. The solution provides reliable transformation of 3D data while maintaining optimal file structure and visual fidelity throughout the conversion process.
STereoLithography File
A file format that was developed by 3D Systems, a global leader in the 3D printing industry, to facilitate rapid prototyping and manufacturing. It is widely used in computer-aided design (CAD), 3D printing, and digital fabrication due to its simplicity and broad compatibility. STL files exclusively represent 3D geometry using a triangular mesh, making them lightweight and easy to process.
Key Features of STL
- Simplicity: STL files are easy to create and read by many software applications and 3D printers, as they only contain the coordinates of the vertices and the normal vectors of the triangles.
- No Additional Attributes: Unlike other 3D formats, STL files do not include details such as face colors, textures, transparency, material properties, or named groups. This means that all STL models appear colorless in their raw form.
- Binary vs. ASCII STL Formats: STL files can be stored in two formats:
- Binary STL - The preferred format due to its compact file size, making it more efficient for storage and processing.
- ASCII STL - A human-readable text format that describes each triangle explicitly, but results in significantly larger file sizes.
- Units of Measurement: The STL format does not define a specific unit of measurement, though most applications interpret the coordinates as being in millimeters. If necessary, our STL files converter can perform automatic unit conversions to match your project’s requirements.
STL File Conversion
Autoconverter and Automesher Application are the best tools for converting STL files because they support a wide range of 3D formats, making it easy to convert STL into other file types like STEP, OBJ, or SKP.
